I was on 401 yesterday in Autopilot at 110 km/hr in left lane passing slower cars when all of a sudden I came across a parked car on shoulder on left and as I passed him, Autopilot slowed rapidly to 80 km/hr and stayed that way for at least about 10 seconds after I passed him before returning to 110 km/h. I find this very dangerous as cars behind would probably wonder what was happening. I'm wondering if it reads the licence plate as a speed sign. They've got to fix this. Anyone else experienced this?
